Inventor: HEIMAN STEPHEN M
IPC: F16K31/04
Filed: 1992-07-21
Abstract: SYSTEM AND METHOD FOR DETERMINING TORQUE OUTPUT OF MOTOR ACTUATED VALVE OPERATORS                 ABSTRACT OF THE DISCLOSURE           A system for determining torque generated by a motor actuated operator driving a partial turn valve including a torque ring replacing the cover of the operator housing, a frictional shaft coupling member coupling the inner circumferential surface of the drive sleeve within the operator housing to the central shaft of a torque plug projecting from the operator through the torque ring.  Two or more stops are provided projecting from the torque ring on either side of the central shaft.  A cross member is provided extending radially outwardly from the central shaft of the torque plug to contact each of the stops when the operator is driven.  A sensor, preferably an array of strain gauges mounted to the central shaft, generates a signal proportional to the torque applied by the operator to the operator housing through the frictional shaft coupling and the torque plug.  The system can be used to calibrate torque switches typically associated with the motor actuator of the operator or corrolate another parameter of the motor actuated operator, such as an actuator spring pack force or displacement which varies with torque load, so as to measure torque indirectly from such parameter.

Inventor: APPOLONIA JACK
IPC: F25D29/00
Filed: 1992-11-02
Abstract: The  present  invention provides  a  cryogenic  freezer  and method  using  a  freezing  chamber  within which  articles  are cooled under the direct application of a cryogen, causing the cryogen  to  vaporize  into  a  cryogenic  vapor.   The  freezing chamber has inlet and outlet plenums through which articles to be  frozen  are  passed  into  and  from  the  freezing  chamber, respectively.  The liquid cryogen is introduced from a make-up tank into the freezing chamber and into direct contact with the articles to be frozen.  Conduits connect the inlet and outlet plenums to a blower that draws air from outside the freezing chamber  and  the  cryogenic  vapor  from  inside  the  freezing chamber to prevent air from entering the freezing chamber.  The cryogenic vapor is drawn from an outlet in the freezing chamber to a recovery unit to be compressed,  purified and liquefied. The resulting liquid cryogen is then fed back to the make-up tank.   In order to prevent  air  from being processed by the recovery unit  along with the cryogenic vapor,  the cryogenic vapor is drawn from the freezing chamber at a level thereof that is as low as possible and such that the mass flow rate of the cryogenic vapor drawn from the freezing chamber is equal to that of the liquid cryogen upon its entry into the freezing chamber.

Title: Buoy for marking submerged boat anchors
Inventor: TKACHENKO ANDREW M
IPC: B63B22/08
Filed: 1993-01-26
Abstract: ABSTRACT     This invention is directed to a buoy for indicating the location of an underwater object, and in particular a submerged boat anchor.  A spherical buoy housing a spring actuated axle and reel mechanism connected to a nylon line is attached by means of an external clasp to a boat anchor prior to setting.  As the anchor is submerged the buoy remains afloat according to the principle of buoyancy.  The nylon line is payed out from the reel as the anchor is lowered.          The buoy remains afloat in a collinear system with the anchor, marking the anchor, and resisting lateral movement which may be caused by wave or wind action.  The tension incurred to the nylon line by the spring force is such that lateral movement of the buoy is restricted while vertical movement is permitted, thus allowing the buoy to remain above the anchor during wave, tidal, or other water level changes or conditions.

Title: Lens markings viewer
Inventor: DORE ROGER
IPC: G01M11/02
Filed: 1994-01-12
Abstract: In the process for producing ophtalmic progressive lenses, it is common practice to inspect lenses using a lamp and the effects of ambiant light refraction to detect surface imperfections as well as for retreiving manufacturers markings. Such markings containing key process information are mandatory for further finishing and cutting processes of the ophtalmic progressive lenses. In this invention, light is generated by a coherent light source at a given wavelenght that may range between 620 and 670 nanometer and collimated prior to being difused over the surface of the lens under inspection. The lens under inspection may be moved at an angle .beta. in the path of the difused light to enhance light refraction occuring onto the markings and other surface imperfections. The light is thus refracted to a projection surface for viewing by the human eye (operator) to clearly examine the markings as well as the surface imperfections before and after coatings and other treatments. In this invention, the optical aparatus is contained into an instrument which encompasses all of the necessary mechanism to enable the examination of most types of ophtalmic lenses.The angle .beta. may be modified by the operator to adapt to different lenses curvature. This is achieved by manipulation of a controller arm until optimum viewing is achieved. The light source intensity as well as focus may be adjusted during the process of examining lenses.
